Josh,
I don’t know I have been running a Horstman HDC5B 2 disk dry clutch for 3 years and have never had a failure! I take it apart every couple of races Maybe change a disk or a steal to get it back into specs and have no problems. I cant imagine spending $ 2000. in clutches. What’s your stall speed does your clutch come unlocked a lot? I set mine at 8600 rpm and it only disengages in 1 of 16 turns according to my Mychron 4.
Love the Horstman 2 disk dry clutch!
